I?) all whom it. may comm;

eitizen fxthef United States, residing at Philadelphia, in the county fPhiIadelphia ii-' and: State of Pennsylvania, have" invented a new anduseful Improvement in Tube- Blowers, of which the following is a specification.

i This'invention relates to a device for blowing'out'boiler-tubes,scalding down engines,

and similar purposes. I The ,'111V6Ilf-1011 conslsts 1n the novel.featu'res, of constructionhereinafter described,-

; pointed out in the claims, andshown in the accompanying. drawings, inwhich-- Figure 1 is a view of the" device in elevation-.TFig. 2 is asectional elevation right angles to Fig. 1. Fig. 3 is an enlargedsection on theline 3-3 of Fig. 2. Fig. 4 is an ,2! enlarged section onthe l-ine'H, of Fig. 2.

Fig. '5v is jadetailenlarged elevation showing a steam spreading disk;Fig. 6 is a section on therline 6 6 ofFig. 5. Fig. 7 is an enlarged.sectional View showing-a nozzle cap gfifenlployed when scalding engines;

a plan view of said cap, the discharge nozzle .belng' shown in dottedlines.

1n these drawings 1 represents a threequarter inch gas pipe, in one endof which'is 130 threaded a coupler 2 which carries a suitable valvecasing 3, to which is connected a steam hose 4'. To an end of thecoupler 2 is secured a; wooden handle5 from which projects'athree-eighthinch" gas pipe 6 upon the '35 free end of-which .is secured either awooden or metal .handle 7. Upon the other end. of the pi e l'oppositethe handle 5 is threaded a discharge nozzle 8 the upper end or rose ofwhich isprovided with three "or more ec eent fically' arrangedperforations 8. This no'zzle carries anddischarges into a sectionalcasing 9, said-sections carrying respectively,

cross'pieces 9 in which. is vertically jour-' naled a shaft 10 whichcarriesadjacent its lowerl end fan blades 11 and adjacent 'its .upperend a beveled disk 12, the beveled edge 0 which is'provided with aseries of obliquegrooves 12, A semi-spherical flange 13 is carried bythe upper end of the caslng 9. In cleaning out a boiler tube the shaft10, disk 12 and such portion ofthe flange 13 as the diameter of the tubewill admit is in-. serted into the tube, the device being supported bgrasping the wooden handle 5 e5 withthe eft hand and the handle 7 withthe right hand: The valve of the casing 31s Fig. 8 is opened by 'means'of a handle 8*..- Steam ..Be it known; that; I, CHARLEsC. Gnovnn, a.

be'ing'fixe'd to the same shaft to which the 1 fan blades are fixed. 7 v

In scaldlng down an englne, the casing 10 is removed from the nozzle anda cap 14 having. a central opening 14? is threaded on the discharge endof the nozzle 8. The es- '70 cape of steam in a spray through theopening 14" can be regulated by screwing the 'cap so as to bring the topof the cap the proper distance from the discharge end. of 4 the nozzle,as the fineness of the spray will be increased byreducing the spacebetween the perforated end of the cap 14 and the perforated end of thenozzle, it being remembered tha tthe opening 14 is in the center of thecap and the perforations 8 are e'ccentric with respect-to the center ofthe.

end of'the nozzle. Having thus fully described myinvention, what I claimas new and desire to secure by Letters Patent, is I f 1. A device of thekind described comprising a discharge nozzle, a casing carried by saidnozzle, said. casing extending in advance of the nozzle, ashaft'journaled longitudinally in said casing, fan blades'carried 0. bysaid shaft and withinv the casing, the shaft 1 projecting from thecasing, and ,a-beveled disk carried by the shaft' in advance of .the'casing, the beveled portionof said disk being provided grooves.

2. A device of the kind described compris- 7 ing a discharge nozzle,theend of said noz" zle being provided witheccentrically placedperforations,a casing adapted to be threaded upon said nozzle, a semisp'herica'l flange carried by the free end of the casing, a'shaftjournaledin and rojecting'from the free end of the casing, anblades'carried. by said shaft within the casing, and a disk fixed uponthe outer end portion of said shaft, the

inner face of the disk being beveled, and pro-v vided'with obliquelyarranged p v v CHARLES C.

grooves.
